Don't start changing your mind that W6 is an amazing sub. Don't start thinking of something else because some idiot doesn't know how to run subs and blew them. If you blew a JL sub three times your obviously doing something wrong to abuse the sub etc. JL=Great Products hands down. I say go with that 13 W6 and you'll be so extremely happy.
Yeah def user error, . I've had my 13w7 running for 9 months now and it performs just as well as the day i installed it. JL makes sum of the best subs out there and u can't go wrong w/ the w6.
